Related Art

In 5G system, in order to support more demanding Ultra Reliable and Low Latency Communication (URLLC) traffic, for example, with higher reliability (e.g., a target BLER of 10{circumflex over ( )}-6) or with lower latency (e.g., 0.5-1 ms), a study item (SI) of URLLC advancement in New Radio (NR) Release 16 was approved at 3^(rd) Generation Partner Project (3GPP) Radio Access Network (RAN) #80 Plenary Session. One focus of the study is how to realize lower transmission latency and higher transmission reliability of Physical Uplink Shared CHannel (PUSCH)/Physical Downlink Shared CHannel (PDSCH). In order to support demands of higher reliability and lower latency of URLLC traffic, 3GPP NR Rel-16 system has agreed to adopt a transmission scheme based on nominal repeat transmission in uplink transmissions. When a nominal repeat transmission crosses boundary of a sot or a Downlink/Uplink (DL/UL) switching point, it is divided into two actual repeat transmissions.

SUMMARY

Flexible symbols and dynamic UL/DL configuration have been introduced into 3GPP NR system. So how to design a repeat transmission scheme is a key problem to be solved considering the influence of flexible symbols and dynamic UL/DL configuration.

In view of the above problem, the present disclosure provides a solution. In the description of the above problem, a repeat transmission is illustrated as an example. The present disclosure is also applicable to a single (i.e., non-repetitive) transmission scenario to achieve similar technical effects in a repeat transmission. Besides, a unified solution for different scenarios (including but not limited to repeat transmission scenarios and single transmissions) can also help reduce hardware complexity and cost. It should be noted that the embodiments of a User Equipment (UE) in the present disclosure and the characteristics of the embodiments may be applied to a base station if no conflict is incurred, and vice versa. The embodiments of the present disclosure and the characteristics of the embodiments may be mutually combined if no conflict is incurred.

Embodiment 3

Embodiment 3 illustrates a schematic diagram of an example of a radio protocol architecture of a user plane and a control plane according to one embodiment of the present disclosure, as shown in FIG. 3 . FIG. 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture of a user plane 350 and a control plane 300. In FIG. 3 , the radio protocol architecture for a first communication node (UE, gNB or an RSU in V2X) and a second communication node (gNB, UE or an RSU in V2X), or between two UEs is represented by three layers, which are a layer 1, a layer 2 and a layer 3, respectively. The layer 1 (L1) is the lowest layer and performs signal processing functions of various PHY layers. The L1 is called PHY 301 in the present disclosure. The layer 2 (L2) 305 is above the PHY 301, and is in charge of the link between a first communication node and a second communication node, as well as two UEs via the PHY 301. L2 305 comprises a Medium Access Control (MAC) sublayer 302, a Radio Link Control (RLC) sublayer 303 and a Packet Data Convergence Protocol (PDCP) sublayer 304. All the three sublayers terminate at the second communication node. The PDCP sublayer 304 provides multiplexing among variable radio bearers and logical channels. The PDCP sublayer 304 provides security by encrypting a packet and provides support for a first communication node handover between second communication nodes. The RLC sublayer 303 provides segmentation and reassembling of a higher-layer packet, retransmission of a lost packet, and reordering of a data packet so as to compensate the disordered receiving caused by HARQ. The MAC sublayer 302 provides multiplexing between a logical channel and a transport channel. The MAC sublayer 302 is also responsible for allocating between first communication nodes various radio resources (i.e., resource block) in a cell. The MAC sublayer 302 is also in charge of HARQ operation. The Radio Resource Control (RRC) sublayer 306 in layer 3 (L3) of the control plane 300 is responsible for acquiring radio resources (i.e., radio bearer) and configuring the lower layer with an RRC signaling between a second communication node and a first communication node device. The radio protocol architecture of the user plane 350 comprises layer 1 (L1) and layer 2 (L2). In the user plane 350, the radio protocol architecture for the first communication node and the second communication node is almost the same as the corresponding layer and sublayer in the control plane 300 for physical layer 351, PDCP sublayer 354, RLC sublayer 353 and MAC sublayer 352 in L2 layer 355, but the PDCP sublayer 354 also provides a header compression for a higher-layer packet so as to reduce a radio transmission overhead. The L2 layer 355 in the user plane 350 also includes Service Data Adaptation Protocol (SDAP) sublayer 356, which is responsible for the mapping between QoS flow and Data Radio Bearer (DRB) to support the diversity of traffic. Although not described in FIG. 3 , the first communication node may comprise several higher layers above the L2 layer 355, such as a network layer (e.g., IP layer) terminated at a P-GW of the network side and an application layer terminated at the other side of the connection (e.g., a peer UE, a server, etc.).

Embodiment 4

Embodiment 4 illustrates a schematic diagram of a first communication device and a second communication device in the present disclosure, as shown in FIG. 4 . FIG. 4 is a block diagram of a first communication device 410 and a second communication device 450 that are in communication with each other in access network.

The first communication device 410 comprises a controller/processor 475, a memory 476, a receiving processor 470, a transmitting processor 416, a multi-antenna receiving processor 472, a multi-antenna transmitting processor 471, a transmitter/receiver 418 and an antenna 420.

The second communication device 450 comprises a controller/processor 459, a memory 460, a data source 467, a transmitting processor 468, a receiving processor 456, a multi-antenna transmitting processor 457, a multi-antenna receiving processor 458, a transmitter/receiver 454 and an antenna 452.

In the transmission from the first communication device 410 to the second communication device 450, at the first communication device 410, a higher layer packet from the core network is provided to a controller/processor 475. The controller/processor 475 provides a function of the L2 layer. In the transmission from the first communication device 410 to the first communication device 450, the controller/processor 475 provides header compression, encryption, packet segmentation and reordering, and multiplexing between a logical channel and a transport channel, and radio resources allocation to the second communication device 450 based on various priorities. The controller/processor 475 is also responsible for retransmission of a lost packet and a signaling to the second communication device 450. The transmitting processor 416 and the multi-antenna transmitting processor 471 perform various signal processing functions used for the L1 layer (that is, PHY). The transmitting processor 416 performs coding and interleaving so as to ensure an FEC (Forward Error Correction) at the second communication device 450, and the mapping to signal clusters corresponding to each modulation scheme (i.e., BPSK, QPSK, M-PSK, M-QAM, etc.). The multi-antenna transmitting processor 471 performs digital spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming on encoded and modulated symbols to generate one or more spatial streams. The transmitting processor 416 then maps each spatial stream into a subcarrier. The mapped symbols are multiplexed with a reference signal (i.e., pilot frequency) in time domain and/or frequency domain, and then they are assembled through Inverse Fast Fourier Transform (IFFT) to generate a physical channel carrying time-domain multi-carrier symbol streams. After that the multi-antenna transmitting processor 471 performs transmission analog precoding/beamforming on the time-domain multi-carrier symbol streams. Each transmitter 418 converts a baseband multicarrier symbol stream provided by the multi-antenna transmitting processor 471 into a radio frequency (RF) stream. Each radio frequency stream is later provided to different antennas 420.

In the transmission from the first communication device 410 to the second communication device 450, at the second communication device 450, each receiver 454 receives a signal via a corresponding antenna 452. Each receiver 454 recovers information modulated to the RF carrier, converts the radio frequency stream into a baseband multicarrier symbol stream to be provided to the receiving processor 456. The receiving processor 456 and the multi-antenna receiving processor 458 perform signal processing functions of the L1 layer. The multi-antenna receiving processor 458 performs receiving analog precoding/beamforming on a baseband multicarrier symbol stream from the receiver 454. The receiving processor 456 converts the baseband multicarrier symbol stream after receiving the analog precoding/beamforming from time domain into frequency domain using FFT. In frequency domain, a physical layer data signal and a reference signal are de-multiplexed by the receiving processor 456, wherein the reference signal is used for channel estimation, while the data signal is subjected to multi-antenna detection in the multi-antenna receiving processor 458 to recover any the second communication device-targeted spatial stream. Symbols on each spatial stream are demodulated and recovered in the receiving processor 456 to generate a soft decision. Then the receiving processor 456 decodes and de-interleaves the soft decision to recover the higher-layer data and control signal transmitted on the physical channel by the first communication node 410. Next, the higher-layer data and control signal are provided to the controller/processor 459. The controller/processor 459 performs functions of the L2 layer. The controller/processor 459 can be connected to a memory 460 that stores program code and data. The memory 460 can be called a computer readable medium. In the transmission from the first communication device 410 to the second communication device 450, the controller/processor 459 provides demultiplexing between a transport channel and a logical channel, packet reassembling, decryption, header decompression and control signal processing so as to recover a higher-layer packet from the core network. The higher-layer packet is later provided to all protocol layers above the L2 layer, or various control signals can be provided to the L3 layer for processing.

In the transmission from the second communication device to the first communication device, at the second communication device 450, the data source 467 is configured to provide a higher-layer packet to the controller/processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to a transmitting function of the first communication device 410 described in the transmission from the first communication device 410 to the second communication device 450, the controller/processor 459 performs header compression, encryption, packet segmentation and reordering, and multiplexing between a logical channel and a transport channel based on radio resources allocation so as to provide the L2 layer functions used for the user plane and the control plane. The controller/processor 459 is also responsible for retransmission of a lost packet, and a signaling to the first communication device 410. The transmitting processor 468 performs modulation mapping and channel coding. The multi-antenna transmitting processor 457 implements digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, as well as beamforming. Following that, the generated spatial streams are modulated into multicarrier/single-carrier symbol streams by the transmitting processor 468, and then modulated symbol streams are subjected to analog precoding/beamforming in the multi-antenna transmitting processor 457 and provided from the transmitters 454 to each antenna 452. Each transmitter 454 first converts a baseband symbol stream provided by the multi-antenna transmitting processor 457 into a radio frequency symbol stream, and then provides the radio frequency symbol stream to the antenna 452.

In the transmission from the second communication device 450 to the first communication device 410, the function of the first communication device 410 is similar to the receiving function of the second communication device 450 described in the transmission from the first communication device 410 to the second communication device 450. Each receiver 418 receives a radio frequency signal via a corresponding antenna 420, converts the received radio frequency signal into a baseband signal, and provides the baseband signal to the multi-antenna receiving processor 472 and the receiving processor 470. The receiving processor 470 and multi-antenna receiving processor 472 collectively provide functions of the L1 layer. The controller/processor 475 provides functions of the L2 layer. The controller/processor 475 can be connected with the memory 476 that stores program code and data. The memory 476 can be called a computer readable medium. In the transmission from the second communication device 450 to the first communication device 410, the controller/processor 475 provides de-multiplexing between a transport channel and a logical channel, packet reassembling, decryption, header decompression, control signal processing so as to recover a higher-layer packet from the UE 450. The higher-layer packet coming from the controller/processor 475 may be provided to the core network.
